This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The automotive torque converter is a fluid coupling device used to transfer power, with multiplication of torque, from the engine to the transmission. Cavitation is a limiting factor in torque converter design, thus a reason for study. A three dimensional, multi-phase Reynolds-averaged Navier-Stokes computational tool is applied to model performance and cavitation in the torque converter. Cases are run for both single and multi-phase conditions, for two different speed ratios, for which performance parameters are compared to experimental data. Analysis includes that for several blade designs, two of which in detail. Periodic flow conditions were assumed, using a body force and a mixing plane approach for blade row coupling. In comparison to experimental results, the solutions found using the body force approach were accurate for some geometry configurations, however not for all. The mixing plane approach served to better conserve flow properties, and provided results of higher accuracy. An analysis of the flow features including vapor cavities, along with the numerical results are discussed in detail.

Download or read book Detecting and Predicting the Onset of Cavitation in Automotive Torque Converters written by Darrell L. Robinette and published by . This book was released on 2007 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: An automated torque converter dynamometer test cell was developed to characterize the effect of torque converter design parameters on the onset of cavitation and noise. A nearfield acoustical technique was utilized to acquire cavitation noise occurring within the torque converter during a standardized stall speed sweep test. After post processing the noise data, the onset of cavitation was readily identified by a sudden increase in filtered sound pressure level. This technique was applied to a wide range of design and stall operating conditions. The effects of the design parameters of diameter, torus dimensions, and pump and stator blade designs were determined.
Book Synopsis Computational Fluid Dynamics in Support of the Large Cavitation Channel by :
Download or read book Computational Fluid Dynamics in Support of the Large Cavitation Channel written by and published by . This book was released on 1992 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project is to use computational fluid dynamics to examine the flow around three Schiebe head forms: 2 inches, 10 inches, and 20 inches in diameter. The flow around the 20-inch head form was examined experimentally in the Large Cavitation Channel by making laser Doppler velocimetry measurements. Computational analysis was used to determine the flow around all three head forms. The computational results and the experimental results were compared. The objective of the comparison was to determine if a computational model could be used to represent accurately a physical model in a test tunnel. The results showed that both viscous and inviscid flow calculations represented the experiment well. The inviscid analysis was much less costly in time and resources while still providing useful results. inviscid flow calculations seem to be the best choice for a preliminary prediction technique to support experimental investigations. This report presents a description of the experimental and computational methods used, a detailed comparison of results, and an analysis of the comparison. computational fluid dynamics, Large Cavitation Channel, Schiebe, cavitation head forms, laser Doppler velocimetry.
